# Outputs an expression.

# Using the `echo` tag is the same as wrapping an expression in curly brackets (`{{` and `}}`). However, unlike the curly
# bracket method, you can use the `echo` tag inside [`liquid` tags](/docs/api/liquid/tags/liquid).
#
# > Tip:
# > You can use [filters](/docs/api/liquid/filters) on expressions inside `echo` tags.
